What it does:

Adds a page to the Form Folder. The page does not automatically appear in the form but it can be referenced in other pages or by fields within the form itself e.g. the Rich Text Field can be used to link to the page within the form.

Example:

<Edit tab> notes:

A page within a Form Folder has the usual Edit sub-tabs of Default, Categorization, Dates, Creators, and Settings. Thus, for example, it can be excluded from the navigation* list of the form.

*A navigation list will appear under the Form Folder if an image or a page (as above) is added to the Form Folder's content.
